For accessibility, I'm trying to add a tabindex attribute to the captcha image.

Here is the script I'm using:

document.addEventListener("DOMContentLoaded", function(){    

document.getElementById("ctl00_ContentContainer_EntityFormControl_aeace8755f5aec118f8f000d3a5b28d1_EntityFormControl_aeace8755f5aec118f8f000d3a5b28d1_EntityFormView_captcha_CaptchaImageUP").tabIndex = 0;

alert(‘page loaded successfully’);

});

The script can't seem to find the image tag by the id. What am I missing here?

Hello...

We've been using RadCaptcha (version 2010 Q1) control on a site for some time, but today when we've had higher load of visitors trying to confirm the displayed code, it wouldn't be accepted, but another code was displayed.

It would take up to a 10 or so entries for the code to be accepted.
Control is located inside update panel, as I've read on one of posts here that should be, it is the only control on the page.
And it wasn't that much people loading, maybe 30 people entering and clicking in 5 minutes.

Also, sometimes Captcha image is not loaded at all.

No help with restarting pool, IIS, etc.

This didn't use to happen on development or testing or live location previously, so it's unclear why sudden.
Are there some updates done between versions 2010.1 and 2010.2 that might help with this?

Thanks in advance...

I can not understand my mistakes, can you help me know if they are delaclariones or imports? I already incorporated the ASP.net code in the design on my Index.aspx page, but when I added the aspx.vb code (visual Basic) I got errors. (attached image)

I have used the Telerik RadCaptcha control in a number of projects and can never get a skin to work with it. All other controls are using the skin defined in the Web.config file in the key:

<add key="Telerik.Skin" value="Bootstrap"/>

 

Does anyone have any idea why the RadCaptha is the only control that doesn't follow this in my projects?

Hello,

We have a SharePoint 2010 environment.  We put the  Telerik CAPTCHA to a web part but are experiencing issues with WFE server(s) hanging at random times when the “Next Image” was used.  It would always come up the first time and could be successfully used but then randomly it would not work when ‘new image’ was requested from the link and it will just hang.

We would get the following error:  Uncaught Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.

It works when there is only one WFE is involved.  We have multiple WFEs and it would fail randomly.  

Any idea/thoughts about the issue?

Thanks,

Ricky

I have a form with a set of fields including 1 captcha. I noticed Page.IsValid is always false if RadCaptcha1.IsValid is false even if all other validators for the other fields are passed.

Is it possible for the Page.IsValid to be true so that it is possible of me to find out if the other fields are really valid without I having to do one-by-one server validation check on individual fields?

How can I center the actual captcha image with the text box and message to "Type the code from the image?"

I have enclosed a screen capture of what it looks like now and as you can see it looks awkward with the captcha image left aligned with the text box and text centered. I'd like everything to be centered.

Thanks for your help!
